Abstract

The invention relates to a method for preparing 1,3-diglyceride through enzymolysis, and belongs to the technical field of 1,3-diglyceride. The method comprises the step of adding ethanol or / and chelating agent in TAG, water and Candida antarctica lipase A to form a hydrolysis system. According to the method, the chelating agent is added in the TAG hydrolysis system to remove metal ion (mainly from the TAG), thereby reducing the inhibiting effect of the metal ion to the enzyme activity and improving the hydrolysis rate; after ethanol and the chelating agent are simultaneously added, not only is the selection tendency of the Candida antarctica lipase A to 2 position of the TAG improved and the reaction time shortened, but also the improvement range of the hydrolysis speed is further increased; therefore, ethanol plays the effect of promoting the chelating agent to improve the hydrolysis speed.

Description

technical field

[0001] The invention relates to a method for preparing 1,3-diglyceride by enzymatic hydrolysis, and belongs to the technical field of preparation of 1,3-diglyceride. Background technique

[0002] Fat is an important part of human diet, and it undertakes functions such as providing energy for the body and improving food flavor during food processing. With the development of the economy and the improvement of people's living standards, the oil intake of Chinese residents is increasing day by day. Many studies have shown that excessive intake of oil will increase the risk of metabolic syndrome such as atherosclerosis, type 2 diabetes, hyperlipidemia, and hypertension, which seriously threatens the health of the body.

[0003] 1,3-Diglyceride (DAG) is the main component of natural oils, and there is no significant difference between its color, energy density, odor, stability and bioavailability in the body and traditional triglyceride (TAG). difference. Many ...
